Abstract (en)
[origin: EP2565673A1] The invention refers to a device for determination of a position of an object by means ultrasonic waves, comprising at least one ultrasonic sensor for receiving ultrasonic signals from the object und computing means for computing the position of the object based on the received ultrasonic signals. At least one laser unit for generating a pulsed laser beam is provided, wherein said pulsed laser beam being directed to the object and adapted to cause at a surface of the object vibrations, by which the object is excited to generate ultrasonic signals. The invention also relates to a method for determination of a position of an object by means of ultrasonic waves, wherein by at least one ultrasonic sensor ultrasonic signals are received from the object, and based on the received ultrasonic signals, the position of the object is computed. A pulsed laser beam is generated by at least one laser unit, said laser beam is directed to the object and by means of the pulsed laser beam vibrations are caused at a surface of the object, wherein the object is excited to generate the ultrasonic signals.
